Harnessing the diversity of digital herbarium data to generate and to test novel predictions

Understanding the effects of changing climate on the timing of key life cycle events is a critical issue that has ecological ramifications not only for individual species, and may also produce broad changes in not only the timing of flowering, but also in the risk of frost damage to floral tissues and in the distribution of floral diversity throughout the growing season over space. Dr. Park demonstrates a series of novel analysis that capitalize on the unparalleled taxonomic diversity, spatial breadth, and temporal depth of data derived from historical plant specimens to evaluate the ecological impacts of climate (and climate change) on an unprecedented array of taxa, as well on the collective ecological properties of the floras they constitute. We used this data to examine the aspects of climate that best predict changes in the timing of flowering among 2,468 distinct North American taxa, conduct the first continental assessment of the risk of frost exposure by floral tissues throughout North America, and also evaluate the manner in which local floras differ in the structure and temporal distribution of their floral diversity along regional temperature gradients.

Dr. Isaac Park is an Assistant Project Scientist and Co-PI on an NSF grant (Phenological sensitivity to climate across space and time: harnessing the diversity of digital herbarium data to generate and to test novel predictions). Isaac earned his Ph. D. in Geography in 2015 from the University of Wisconsin-Milwaukee. His collaborative research uses digital records of historical plant specimens to evaluate the factors influencing historical and contemporary flowering times within and among flowering plants across the continental U.S., with a particular focus the effects of climate on altering the structure of regional flowering displays.
